Gelco Chimney Cleaning in Lennox, CA | Imperial Chimney
We provide independent Gelco chimney cleaning and inspection across Lennox’s 90304 ZIP code, and the thing that separates our work here has nothing to do with marketing. It has to do with what we find inside the flues of Lennox’s 1940s and 1950s stucco bungalows: cracked clay tile liners, corroded dampers, and prefab chase venting that hasn’t been opened since Johnson was in office. We’re not authorized, sponsored, or endorsed by Gelco. We’re a local crew that knows these systems cold, and we’ll tell you straight what yours needs. Call (866) 253-3809 for a free estimate.
Why Lennox Residents Choose Us for Gelco Service
Noel Carrasco, our owner, has been cleaning and inspecting chimneys across the LA basin for going on two decades. He grew up a few blocks from Wilshire and Vermont, trained in HVAC and building systems at LATTC, and got pulled into chimney work by an instructor who saw something in him worth keeping. We’ve since expanded to offer Gelco in Hawthorne and surrounding communities. That means when we show up to a Lennox bungalow with a Gelco fireplace, we already know what we’re likely to find before we set foot on the roof.
We’re an independent service provider, so our allegiance is to you, not to a manufacturer’s warranty flowchart. That said, we keep OEM Gelco parts in rotation when they’re available and quality aftermarket equivalents for common wear items like dampers, glass, and gaskets. For Lennox homeowners, that means shorter turnaround when a damper seizes or a gas insert pilot won’t hold. We also carry the full Gelco sales & service knowledge base from years spent inside these fireboxes, so our diagnostics are specific, not guesswork.
One company, start to finish. Sweep, inspection, repair. Nobody hands your chimney off to a sub they met that morning.

Common Gelco Chimney Cleaning Problems We Solve in Lennox
Gelco fireplaces age a particular way in Lennox. Here’s what we actually see:
- Damper and hinge corrosion from marine-layer dampness. Lennox sits close enough to LAX that overnight fog rolls through on a regular cycle. That moisture settles into chimneys and works on metal parts. On rarely used Gelco fireplaces, dampers stiffen or seize open. A stuck-open damper lets conditioned air escape year-round and lets damp air in, which accelerates the problem.
- Cracked or spalled firebox refractory panels. The 1940s through 1960s masonry surrounds in Lennox’s small-lot bungalows have cycled through decades of intermittent burn-and-cool. Refractory panels crack, brick spalls, and the firebox slowly loses its ability to contain heat safely. We inspect for this on every Gelco cleaning visit.
- Gas insert burner and pilot fouling from months of disuse. Lennox winters are mild, so gas inserts sit idle for stretches. Dust, spider webs, and oxidation build up in the burner ports and pilot assembly. When you finally start the unit in November, it stutters or won’t hold a flame. A thorough cleaning of the burner and pilot usually fixes it.
- Soot and creosote buildup in old prefab chase venting. Early Gelco prefab fireplace systems in Lennox were often installed and then never inspected again. Chase venting collects soot that compresses into a hard glaze. We clean it out and evaluate whether the chase itself is still sound.
- Cracked clay tile flue liners. This one shows up so often in Lennox that it gets its own section below. It’s the single most important finding on many of our Gelco service calls here.
Gelco Service in Lennox: What Local Conditions Mean for Your Equipment
Here’s something true about Lennox that isn’t equally true five miles north. The original chimney flues in these 1940s through 1960s bungalows were built with clay tile liners, and those liners crack. Not occasionally. Routinely. Decades of settle-and-heat cycles work on the mortar joints while the marine-layer moisture does its own quiet damage. By the time we arrive for what the homeowner thinks is a simple cleaning, that liner often has fractures running through it that can’t be seen without a camera.
So we don’t put a brush down a Lennox flue blind. We run a camera check first on any fireplace of this era, Gelco or otherwise. If the liner’s intact, we clean and move on. If it’s cracked, you see the footage on our screen before you spend a dime. This matters because Lennox’s lots are packed tight, and the same chimney that vents your Gelco fireplace also holds heat from every fire you’ll burn. A cracked liner isn’t a cosmetic issue. It’s a fire-safety issue. We tell you what we found, and we show you. If it’s in the flue, we’ll tell you straight, no upsell, no vague “concerns.”
Gelco Models & Products We Service in Lennox
Our crew services the Gelco lineup Lennox homes actually have: gas fireplace inserts, prefab fireplace and chase systems, and wood-burning fireplace units, including aftermarket-style glass and trim assemblies. We also provide Inglewood Gelco service with the same expertise. We know which dampers fit which prefab chase, where the fail points are on early gas inserts, and when a repair makes more sense than a rebuild.
Parts sourcing is straightforward: OEM Gelco components when available, durable aftermarket equivalents for wear items. We stock common dampers, gaskets, and glass locally so Lennox turnaround stays fast. We only recommend replacement when the firebox or chase is structurally compromised. Built to last past the visit is the standard, not the slogan.

AfterGelco Service Pricing in Lennox
Gelco chimney cleaning in Lennox generally runs between $180 and $340. A Level 2 camera inspection adds $150 to $350, and damper repair lands around $150 to $400 depending on whether it’s a hinge, crack, or full assembly. Gas fireplace service runs $125 to $350. If the flue liner needs relining after a camera check, that’s $2,500 to $5,500, though we recommend it only when the existing liner is genuinely compromised.
What drives cost here: roof access down narrow side yards, the condition of the damper and glass, and whether we’re cleaning a prefab chase or a full masonry flue. Every estimate includes the camera check and a photo report, so you see the same thing we see before any repair is quoted. Call (866) 253-3809 and we’ll give you an exact number for your Lennox fireplace.

FAQs – Gelco Chimney Cleaning in Lennox
We’ll inspect the firebox, pilot assembly, and burner, then run a camera check up the flue before any cleaning happens. On a unit that’s been idle, expect us to remove dust and oxidation from the burner ports, check the damper for marine-air corrosion, and confirm the venting is clear. If the liner’s cracked, you’ll see the footage and we’ll discuss repair options before anything else.
Because most Lennox fireplaces from the 1940s through 1960s sit on original clay tile liners, and those liners crack after decades of settle-and-heat cycles plus damp marine air. A cracked liner exposes surrounding framing to heat and combustion gases. It’s the difference between a safe fire and a slow-burning problem inside your walls.
Yes. Lennox lots are tight and fences are shared, so we work from the roof with drop cloths layered over adjoining property lines and around the chase. Soot stays contained on our side. We do it this way routinely on the narrow side yards off shared driveways throughout the 90304 pocket.
Usually, yes. We free seized hinges, lubricate the mechanism, and replace worn gaskets before recommending a full damper replacement. If the damper blade itself is cracked or warped, replacement is the honest call. We’ll show you what we found and quote both options. Call (866) 253-3809 and we’ll take a look.
It is, especially for masonry chimneys close to LAX. Marine-layer moisture doesn’t look dramatic, but it works on mortar and brick over years. Waterproofing seals the masonry against absorption and slows the spalling we see on many Lennox chimneys. It’s a modest cost against the price of rebuilding a chimney crown or firebox down the line.
